Filing a probate application isn't the end of the story if something changes afterward. A newly discovered bank account, a mistaken estimate of value, or even a will that turns up after you've already applied without one — all of these can mean the application on file with the court no longer reflects reality. The good news is that Ontario's probate process allows for both amending a probate application and, in the right circumstances, withdrawing one entirely.
This article explains why applications sometimes need to change, what amending and withdrawing generally involve, and what to do if you're in this position.
Why Probate Applications Sometimes Need to Change
An application for a Certificate of Appointment of Estate Trustee is built on the information available at the time it's prepared — an inventory of assets, an estimated value, and a proposed applicant. Any of that can shift:
- A new asset is discovered after the application is filed (another account, an investment, a property interest no one knew about)
- The estimated value of an asset turns out to be wrong
- A will is found after an application was filed on the basis that there was none — or the reverse
- The person who applied needs to be replaced, or another eligible applicant needs to be added
Amending an Application Already Filed
Ontario's probate process, governed by the Rules of Civil Procedure for estate applications, generally allows for corrections and updates to be filed with the court after the original application — commonly to add newly discovered assets or correct an error in what was originally reported. The specific documents and steps required can vary depending on what needs to change and where the application stands, so this is an area where checking with the court office handling the estate, or getting legal advice, saves real time.
Withdrawing an Application Entirely
Sometimes the right move isn't a correction but starting over. Common reasons an application might need to be withdrawn include:
- The wrong person applied, and someone with a better claim under Ontario's statutory order of priority needs to apply instead
- A will was located after an application proceeded on the basis the deceased died without one
- The applicant and other interested parties reach an agreement about who should act, different from what was originally filed
Whether withdrawal is available — and what happens next — depends on where the application stands in the court's process. This isn't something to guess at; confirm the current status and options with the court registry or a lawyer before assuming an application can simply be pulled back.
What Happens to Estate Administration Tax If the Value Changes
Estate Administration Tax is calculated on the estate's value as of the date of death, so a correction to that value can change the tax owing. Ontario also requires an Estate Information Return to be filed with the Ministry of Finance after a certificate is issued, confirming the value used for the tax calculation.
If the estate's value changes after that return has already been filed — for example, because a new asset surfaces — the return itself may need to be updated. Requirements and any applicable deadline for updating a return already on file can change, so verify the current process directly with the Ministry of Finance or a lawyer rather than relying on assumptions.
Practical Steps If You Need to Amend or Withdraw
- Document exactly what changed — the new asset, the corrected value, or the new information about a will — with supporting paperwork where possible.
- Contact the court office handling the application to confirm what form the correction or withdrawal needs to take given where the application currently stands.
- Get legal advice before filing anything further, especially if the change affects who should be applying, the estate's tax position, or whether other interested parties need to be notified.
- Keep beneficiaries informed of any material change to the application — transparency here tends to prevent disputes later.
Frequently asked questions
Do I need a lawyer to amend or withdraw a probate application?
It isn't always mandatory, but this is an area where a mistake can create real delay or expose an estate trustee to personal risk — particularly around Estate Administration Tax and who has authority to act. Legal advice is generally worth it.
What if I find a new asset after the certificate has already been issued?
You'll generally need to address both the court record and the Estate Information Return, since the tax was calculated on the value reported at the time. Confirm the current process with the Ministry of Finance or a lawyer, since requirements can change.
Can a probate application be withdrawn just because beneficiaries disagree with the applicant?
Not on its own. Disagreement among beneficiaries isn't automatically a basis to withdraw an application — there needs to be a proper legal reason, such as a better-ranked applicant under the statutory order of priority or a genuine error in the original filing.
Is there a deadline to correct a mistake in a probate application?
There's no single universal deadline we can point to here — it depends on the nature of the correction and where the application stands. The safer approach is to raise the issue as soon as it's discovered rather than wait.
